Product Description The 1027 Flat Coin Vibration Motor is an ultra-compact, disc-shaped motor designed to provide haptic feedback in small electronic devices. Commonly known as a "pager motor," its low profile and lightweight design make it the industry standard for mobile phones, smartwatches, and wearable fitness trackers. Unlike traditional cylindrical motors with external weights, this motor features an internal eccentric rotating mass (ERM) that generates high-frequency vibrations while being completely enclosed. At Robogears, we recommend this motor for any project where space is at a premium and a silent, tactile alert is required.

Key Highlights
Ultra-Low Profile: With a thickness of only 2.7mm, it can be easily embedded into slim enclosures, handheld devices, and even smart clothing.
Self-Adhesive Backing: Features a pre-applied strong adhesive tape on the back, allowing for quick and secure mounting directly onto PCBs or plastic housings.
High Efficiency: Optimized to work at 3V, drawing very low current, which makes it ideal for battery-powered IoT and wearable applications.
Encapsulated Design: The rotating parts are fully enclosed within the metal "coin" housing, preventing dust or debris from interfering with the motor's performance.
Flexible Lead Wires: Comes with thin, pre-stripped, and colour-coded lead wires for easy soldering to your control board or battery.

Installation Tip from Robogears: Because this is a brushed DC motor, it can generate small amounts of electrical noise. When connecting it to a microcontroller like an Arduino, we recommend using a small NPN transistor (like a PN2222) or a MOSFET to drive the motor, as the motor's starting current can exceed the safe limit of a digital I/O pin. Additionally, placing a small flyback diode (like 1N4148) across the motor terminals will protect your sensitive electronics from back-EMF spikes during operation.
